A `12Omega` resitance and an inductance of 0.05/ `piH` with negligible resistance are connected in series. Across the end of this circuit is connected a 130 V alternating voltage of frequency 50Hz. Calculate the alternating current in the circuit and potential difference across the resistance and that across the inductance.
